REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 486,530, dated November 22, 1892.

Application filed March 30, 1889. Serial No, 305,433. (No model.)

To all whom it may concern:

Be it known that I, MYRON R. HUBBELL, a citizen of the, United States, residing at Wolcott, in the county of Lamoille and State of Vermont, have invented certain new and useful Improvements in Reversible Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of refer-.

ence marked thereon, which form a part of this specification.

My invention relates to an improved reversible plow.

It consists of a combination of a reversible mold-board with an adjustable plow-beam and lever for operating the latter. The beam, having a lateral motion, is capable of being swung in either direction. The lever is placed in such a position that the plowman without leaving his station at the handles can readily swing the beam to the right or left side of the plow, and thus adjust and securely lock the draft attachment in its proper position for the right and for the left hand furrows alternately and at such points as will cause the plow to cut the desired width of furrow.

The object of this invention is to furnish a reversible plow that is adapted to fiat-land plowing and one that will turn all the furrows in one direction, thereby leaving the surface of the land smooth and even, and thus doing away with the ridges and gutters that are so objectionable in lands plowed with non-reversible plows.

In the drawings hereto appended similar letters and figures refer to similar parts.

Figure 1 is a side elevation of the plow, showing the same with the mold-board turned to the right, and also showing the arrangement and device for shifting the beam. Fig. 2 is a rear view of the plow, showing the device for locking the mold-board when reversed from one side to the other. Fig. 3 is a drawing of the standard A, showing the projection on which the plate B turns. Fig. t is a view of the plate B, showing the cogs d and f, the lever G, and the manner of its working, also the hole through which the pin passes.

In the drawings, I represents the beam of the plow, secured to the forward end of the standard A by the pin Ct, which passes up through the plate B and beam 1. The rear end of the beam is held in place by the projection b, which fits into the groove d, formed in the plate B. The groove d, sliding laterally on the guide or projection b, allows the beam I to turn on its pivot or pin a. The plate B is securely bolted to the beam I, and on the rear end of the plate B are cogs, into which the cogs on the lower end of the lever G closely fit. The lever G is pivoted to the standard A by the pin 0, the upper end of the lever resting in the notches in the rack H. When the upper end of the lever G is moved in either direction along the rack H, the beam I is turned on its pivot a by means of the cogs at the lower end of the lever G, giving the forward end of the beam I a lateral motion corresponding with the motion of the upper end of the lever G. By moving the lever G along the rack H the plowman can adjust the plo-w so as to cut a wide or a narrow furrow and so as to out both the right and left hand furrows of the same width.

Fig. 2 is, as stated, a rear view of the plow, showing the method of securing the moldboard M in position by means of the doublearmed locking-bar z z. This bar is pivoted to the rear of the top of the standard A at the point at and is shaped at the end of the arms in a suitable manner to engage the lugs 2, fastened at proper points to the inside edges of the mold-board M.

Y is aspring, designed to be of steel, screwed into the top of the standard at the point 5 and bent backward and fastened to the lockingbar at the point 4. The tension of this spring draws the locking-bar up into position on either side as the point 4 is brought past the center of the standard in the desired direction, the purpose being to enable the plowman remaining in his position to lock the mold-board to either side by pushing downward on the locking-bar until the point 4 is carried by the center, as above, when the spring described will draw it up on the opposite side into place, ready to receive and lock the mold-board when reversed by the other arm.

It is obvious that the foot-latch or lockingbar a can be adapted to engage either with the mold-board brace X or with the lugs 2 of the mold-board, as either will effect the same object.

Having thus described my invention, that which 1 claim as new, and desire to secure by Letters Patent, is

1. In a reversible plow, the double lockingbar ,2 z, swiveled to the standard A, in combination with the mold-board lugs 2 2, the spring Y, attached at one end to the standard A, the other end of the spring pivoted to theloekingbar 2 z in such a manner as to draw the outward end of the same upward into position,

ready to engage with the lugs 2 2 of the moldboard M, substantially as described.

2. The combination, in a reversible plow, of
